- Seu-ita ama JOSEPH CHARLEVILLE, OF ST. LOUIS COUNTY, ,MISSOURL LawsPatent No. 84,260', dated Novanta 24, 186s.

IMPROVED STEP-LADDER.

The Schedule referred to in these Letters Patent and making part of thesame.

To all 'whom it may conce/rn:

Be it known that I, JOSEPH CHARLEVILLE, of the county of St. Louis, andState of Missouri, have made certain new and useful Improvements inStep-Ladders andI do hereby declare that the following is a full andclear description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

The nature'of this invention is in the adaptation, to

lan ordinary step-ladder, of a top seat or foot-board, in

such wise that the same may be easily adjusted and secured or removed.

To enable those skilled herein to make and use my said ladder, I willnow` fully describe the same, referring to the accompanying Figure l asa sectional elevation of the ladder, with the foot-board securedthereon; to

Figure 2 as a plan of 'the foot-board when disconnected from the ladder;to

Figure 3 as a det-ail elevation of the tenon-end of the step-ladder railor bar. Y

I construct the step-ladder, A, generally in the usual form, and of theusual materials.

Said ladder has therails or side bars a, and the rounds or steps b, andthe said rails a are connected, by the journal c, withthe brace d. y g

A simple rope, e, may be used, as in other similar ladders, to preventthe rails and bracesfrom spreading unduly.

The parts thus described are known to me to be in common use, and I dohereby expressly disclaim any or all of said parts as my invention.,

My improvements, however, consist in adding to said ladder A the foot orseat-board B,'and for this purpose I arrange the upper end of the railsa with the tenons j, as shown in fig. 3.

To correspond with said tenons f, I cut the mortises gin the seat-boardB, thereby permitting the board B to be easily adjustedon the upper endof the rails at.

In order to further secure and brace the said `seat-` boards, so thatthe same shall not tip when' bearing the weight of a man, I secure, tothebottom side of the seat-board B, the brace-arm G, in a permanentmanner.-

Said arm G curves forward, and abuts on and against the round or step b,thus supporting the rear end of the seat-board. It will be seen that themanner now described of securing the seat-board. B upon the rails c isfirm and strong, and at the same time it may be easily disconnected whennot needed, and the person using the lad der is then relieved of thelabor of carrying a ladder made heavier by the said board B.

Having thus fully described my invention,

The rail a, its tenonl f, in combination with the mortise g of theseat-board B, and the brace G, and step or round, b, substantially asand for the purposes set forth.

In testimony of which invention, I hereunto set my hand, in presence of-JOSEPH CHARLEVILLE. Witnesses:
